Greenhouse market data by country
Published figures for the six markets covered by our market guides. Every number comes from a public source, shown with its year. None of them are SeedMatchGroup estimates or results from our own projects.
Greenhouse structure costs from published studies
Very few public studies give per-m² greenhouse costs, and those that do usually cover one component only. The figures below are for the steel structure alone, not a full installed project.
€15.14 per m²
Structure only: optimized multi-tunnel steel frame, 3.5 m between portal frames, steel and plastic gutter. Excludes cover film, equipment, labour and installation.
Spain (design study) · 2022
€14.21 per m²
Structure only: same study, structural gutter supporting the arches with 4.5 m between portal frames.
Spain (design study) · 2022
For full-project planning ranges, see the greenhouse cost guide, where figures are labelled as planning estimates, not measured data.
Crop yields (tonnes per hectare, 2024)
National averages across all growing systems, open field and protected. They are not greenhouse yields and not a forecast for any project.
